DISK WHEEL FOR VEHICLES.

Specification of Letters Patent.

Application filed November 14, 1918. Serial No. 131,271.

According to my invention, two trefoils preferably constitute the wheel, the circles of the second trefoil being placed on the op-- posite side of the hub, the disposition being such that thetwo trefoils do not coincide; the circles on the one side of the hub occupy the spaces on the other side. The trefoil on one side is equal in strength to a full disk, but lighter. Each disk has a hole in its center.

I provide cross-pieces which are suitably fastened to the wheel rim, one side being bolted or otherwise connected to the disk, while the other side is connected to a circular rim flange, and as the circles or he foils are not opposite to each other, it follows that the rim brackets will be used for a trefoil circle on one side, and the flange on the same bracket on the other side, so that the brackets on one side secure the three circles of trefoil, and on the other the flange is secured in three places to the same brackets.

The hub for such wheel consists of a tube having two ribs or flanges, the trefoil being put on fro'm each side, and a ring flange being then put on and bolted to each side and into the tube flange.

In order that my inventionmay be propor] y understood and readily carried into effect, I have hereunto appended one sheet of drawings, of which- Figure 1 is a side elevation of a wheel made in accordance with and constituting my invention.

Fig. 2 is a transversesection of the same.

Fig. 3 is a side tlOVfltlOll of the wheel with the rim tire. rim flange and one of the trefoils removed, in order to more clearly illustrate the one that remains.

Fig. 4 is a perspective view of one of the Patented Aug. 20, 1918.

rim brackets for carrying the outer circles of the trefoils and the rim flanges, and

Fig. 5 illustrates a side elevation and end view respectively of part of a trefoil showing a lip formed on the apex of the circle, all hereafter more fully referred to and described.

WVith reference to the drawings, A and B indicate the two trefoils which compose the body of the wheel. These trefoils are car-- ried on the hub C of the wheel and are dis posed in such a manner relative with each 4 other that the position of A does not coin cide with the position of B, the circles of the trefoils A on oneside of the hub C occupying the spaces formed by the trefoil B on the other side of said hub. The extremities of the circles comprising the trefoils A and B aforesaid are held rigidly in position-by bolts D or other convenient means. These bolts pass through holes formed in brackets E of channel formation attached to the inner circumference of the rim E of the Wheel by rivets F or such like. The trefoils A and B are both carried on the exterior sides of the brackets, The channel E intervening determines the space between these two devices. The two rim flanges F, G, are carried by the aforesaid bolts 1) laterally and on the exterior side of the two trefoils. T he bolts may be :Illgli'ulltd for strength if found necessary. The hub consists of a sleeve with ribs or flanges IT, I, constituting a bracket of channel formation and terminating on either side with tube extensions H, P, for receiving laterally the centers of the trefoils A andB aforesaid. lnorder to rigidly retain the trefoils centrally in their proper position, hub flanges J, K, are employed and these are placed on the tube extensions H on either side of the hub. Short bolts J pass through'tho hub flanges J, K aforesaid, and. through holes made in the ribs or flanges H, I of the hub sleeve. interposed and clamped between the huhflanges and the ribs or flanges H and I, are the inner central portions of the two trefoils.

Referring to Fig. 5, the trefoils may be formed with an extension K forming a lip on the periphery of the circles of the trefoils which when bent over may consaid extension and these may be used when riveting is resorted to.

Claim: In a Wheel of the type set forth, trefoils 5 constituting the body of the wheel, ribs or flanges hub and hub flanges with bolts for carrying the trefoils in their central position, brackets of channel formation riveted to the formed on a sleeve constituting the rim, the rim flanges with transverse bolts 10 or such like for carrying said trefoils at the apexes of the circles. r

In witness whereof I aflix my signature in the presence of two witnesses. ROBERT BLAKOE. Witnesses:
